To compute the variance, what should one do? Divide the standard deviation by n minus −1. B. Double the standard deviation. C. Take the square root of the standard deviation. D. Square the standard deviation.

D. Square the standard deviation.

Step-by-step explanation:

To compute the Variance of any given set of data given the standard deviation, all we simply do is take the square of the standard deviation.

If for example, the standard deviation of a given set of data is 6, the variance will be 6²=36.

Similarly, standard deviation can be obtained from the variance by simply taking the square root of the variance. e.g. If the Variance of a group of data is 9, the standard deviation is √9 =3.

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
